WATER-CLOSET.

Application filed March 10, 1913.

To all whom it may concern:

Be it known that I, JOHN J. BoYNn, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Water-Closets, of which thefollowing is a specification. .7

This invention relates to a water closet of that type in which thecontents of the bowl vide such water closets with an auxiliaryv siphonor overflow which during the normal condition of the closet Wlll beinactive but which in the event of the main siphon becoming clogged willbecome active and conduct the water from the bowl to the out let of thecloset and thus prevent overflowing the same.

In the accompanying drawings: Figure 1. is a vertical longitudinalsectionof a Water closet embodying my improvements. Fig. 2 is ahorizontal section in line 2-2, Fig. 1.

Similar characters of reference indicate corresponding parts in bothfigures.

Although my invention is applicable to water closets which may bevariously constructed so far as the details are concerned that shown inthe drawings comprises a bowl 1 having an internal flushing rim 2 and awater supply pipe 3 connected with the rear part of this rim. Underneaththe bowl is arranged the outlet 4 for the closet which may be connectedwith the drain or soil pipe in any suitable and well known manner.During the normal operation of the closet the contents of the bowl areremoved therefrom through a main siphon arranged on the rear part of thecloset and having an ascending passage 5 which extends upwardly from thebottom or lower part of the bowl and a descending passage 6 extendingdownwardly from the upper end of the ascending passage 5 to the outlet4.

Upon admitting water into the bowl from the supply pipe and flushing rimso as to cause the water in the bowl and ascending Specification ofLetters Patent;

passage 5 to rise until it escapes into the descending passage 6 asiphonic action is produced in a well known manner which causes thecontents of the bowl to be drawn from the bowl upwardly through theascending passage 5 and discharged downwardly through the descendingpassage 6 and out of the outlet in the waste pipe. After each flushingoperation the water in the bowl sealsthe lower end of the ascendingpassage 5 so as to prevent the escape of any sewer gas from the drainpipe through the main siphon into the building, the level of the waterat this time not rising above the upper ends of the ascending anddescending passages of the main siphon.

It sometimes happens that the main siphon becomes clogged by reason ofchildren dropping tooth or hair brushes, drinking glasses or otherhardsubstances in the bowl so that they are drawn into the ascendingpassage of the main siphon and choke the same. lVhen this occurs thesubsequent addition of water upon opening the flushing valve willeventuallyfill the bowl completely with water and often overflow fromthe latter on to the floor causing damage and inconvenience. To avoidthis an auxiliary siphon or overflow is provided which is preferablyarranged on the front side or part of the closet and consisting of anascending passage 7 extending upwardly from the bottom of the bowl and adescending passage 8 extending downwardly from the upper end of theascending passage 7 to the'outlet 4. The upper ends of the ascending anddescending passages of the auxiliary siphon or overflow are arrangedhigher than the upper ends of the ascending and descending passages ofthe main siphon so that there is no flow through the auxiliary siphon orto flow over the turn or highest part of the main siphon. But if themain siphon is obstructed either completely or to such an eX- tent thatthe water is not carried away from the bowl by the main siphon as fastas it is supplied by the flush pipe then the water will rise in the bowland in the ascending passage of the auxiliary siphon or overflow untilit reaches the highest part of the same after which any additional waterdischarged into the bowl by the flush pipe will flow downwardly throughthe descending passage of the auxiliary siphon or overflow and escapethrough the outlet 4 to the drain or overflow while the water is free tocorrect the defect.

sewer. Inasmuch as the ascending passage of the auxiliary siphon oroverflow is filled with water from the bowl this siphon is water sealedand sewer gas is prevented from passing through the same from the drainor waste pipe into the building. It will thus be noted that so long asthe main siphon is in an operative condition to carry away the contentsof the bowl when the flushing water is supplied thereto, the auxing ofthe room in which the closet is installed. When this abnormal rising ofthe water in the bowl is observed this serves as a signal that somethingis wrong with the main siphon so that a plumber can be called The closetis not intended to be used when only the auxiliary siphon or overflow isavailable since the primary function of the latter is that of a safetydevice to prevent overflowing of the closet and also as an indicator tocall attention to a clogged condition of the main siphon. I

By arranging the auxiliary siphon on the front side of the bowl thecloset can be manufactured at low cost without any unusual diificultyand without detracting from the appearance of the same. The crosssectional area of the auxiliary siphon is also smaller than that of themain siphon so that the auxiliary siphon does not project forwardly fromthe bowl to such an extent as would cause interference therewith and sothat the slow escape of the water through the same in the event of themain siphon becoming clogged will notify the user that the latterrequires attention.

My improved water closet is exceedingly simple in construction, the samecan be produced at a cost no greater than those now ,in common use, andthe same does not require a departure from the usual method ofinstallation.

v I claim as my invention:

1. A water closet comprising a bowl, an outlet below said bowl, a mainsiphon having an ascending passage extending up- -wardl v from thebottom of said bowl and a descending passage extending downwardly fromthe upper end of said ascending passage to said outlet, and an auxiliarysiphon or overflow having an ascending passage tending upwardly from thebottom of the sage to said outlet, and an auxiliary siphon or overflowhaving an ascending passage extending upwardly from the bottom of thebowl and a descending passage extending downwardly from the upper end ofsaid last mentioned ascending passage to said outlet, the upper ends ofthe passages of the auxiliary siphon being arranged higher than theupper ends of the passages of the main siphon and saidmain siphon beingarranged on the rear part of the closet and said auxiliary siphon on thefront part of the closet andthe cross sectional area of said auxiliarysiphon being less than that of said main siphon.

Witness my hand this 7th day of March, 1913.
